5) Stop bit length setting value (K0: 1 bit, K1: 2 bits)
6) RS/CS setting (K0=disable, K1=able)
7) Waiting time for starting transmission (K: 0=Time for about three characters/effective time=Kn
* 0.01
ms (0 to 100 ms))
8) Starting code STX setting value (K0=disable, K1=able)
9) Terminator setting value (K0=cR, K1=cR+Lf, K2=time (24 bits),
K3
=EXT)
10) Reception done judgment time (K:0=immediate/effective time=Kn * 0.01 ms (0 to 100 ms)
11) Modem initialization (K0=Not initialized when the power turns on, K1=Initialized when the power
turns on)
Note
The execution for switching the operation mode of the
communication (between the computer link and the
general-purpose serial communication mode) or the setting for
the communication parameter should be carried out when no
communication is performed.
If these operations are executed in communicating, the data
which is being transmitted will be cancelled, and the reception
error will occur for the data which is being received and this data
may not be received properly.
When the communication parameter is specified, the received
byte number should be specified to the even data of 22 bytes or
smaller. If it is specified to the value larger than 22 bytes or odd
byte, an error occurs in the parameter settings of the MCU.
